repeat The main loop of STRIPS is iterative and continues until a state description is produced that satisfies the goal, γ. The termination test in step 9 produces a substitution, ∑ (possibly empty), such that some conjuncts (possibly none) of γσ appear in S. There can be several sub...
Examples: Tree and graph traversals, divide-and-conquer algorithms like quicksort and mergesort, and problems involving backtracking like solving mazes or puzzles.IterationIterative solutions are generally more efficient in terms of memory and execution time and which involves simple repetition. For the...
Currently, the best published wirelength results are obtained by methods requiring legalization after global placement. FengShui 5.1 [36] uses recursive-bisection with iterative deletion, iterative repartitioning, relaxed rows not aligned with standard cell rows (“fractional cut′”), and a simple Te...
The authors present an algorithm for transforming a linear recursive program with a list constructor in Prolog, whose rules are mutually exclusive to each other, into an iterative program using a while loop without backtracking and unification. In this algorithm the authors decide whether a given ...
